Product Description:

ORI-TECH GEO 40 C is a new generation lubricant, with low-ash content, for stationary gas engines. Only very high –quality, non-conventional hydro treated bases are used in this product, together with latest –generation additives in order to obtain exceptional anti oxidation properties.
Belongs to a new generation of oils that are designed to provide longer times between oil-charges and to minimize jacket, piston and valve wear. It is especially recommended for engines in continuous use, with high-load and heavily- demanding levels. Also, because of its composition, it is compatible with catalyses.
